NXP Semiconductors has announced a new industry-first 28nm RFCMOS radar one-chip IC family for next-generation ADAS and autonomous driving systems. SAF85xx one-chip family combines NXP’s high-performance radar sensing and processing technologies into a single device. It offers tier ones and OEMs flexibility in addressing short, medium, and long-range radar applications to serve ever more challenging NCAP safety requirements. The introduction of the one-chip radar family has added to NXP’s leading radar portfolio, built on more than 15 years of technology leadership and designed to surround drivers in a cocoon of safety to reduce accidents. DENSO Corporation, which works at the forefront of radar technology, has embraced NXP’s latest innovation as its lead customer.

This advanced radar sensing technology plays an essential part in accelerating the development of next-generation ADAS. We know DENSO will extend its leadership position in ADAS by leveraging NXP’s compact high-performance SAF85xx radar SoC.”


NXP’s family of automotive radar SoCs is comprised of high-performance radar transceivers integrated with multi-core radar processors which are built on NXP’s S32R radar compute platform. The SAF85xx offers twice the RF performance and accelerates radar signal processing by up to 40%, compared to NXP’s previous generation. The one-chip family enables 4D sensing for corner and front radar, serving critical safety ADAS applications, such as automated emergency braking, adaptive cruise control, blind-spot monitoring, cross-traffic alert, and automated parking. OEMs will benefit from the increased flexibility it offers in meeting the expanding NCAP safety requirements and the proliferation of radar sensors, which some analyst estimates the project will range to up to five or more per car.

When combined with power management and connectivity solutions from NXP, the system solution flexibly addresses a wide variety of today’s and tomorrow’s OEM needs. Developers can take advantage of the S32R family’s seamless performance scalability as well as its software and hardware design reuse benefits.

Our new radar one-chip family enables the reliable long-range detection of objects and separation of small objects next to larger ones, like a fast-moving motorcycle next to cars and trucks on a busy multi-lane highway. Its small form factor allows our customers to build radar sensor modules that are up to 30 percent smaller, enabling global suppliers of ADAS systems, like DENSO, to expand the potential of radar safety through this powerful new technology.”

NXP’s 3rd Generation RFCMOS Radar Platform

  • Built on the proven RFCMOS expertise of NXP, which was the first to ramp to high-volume series production for automotive radar and has already shipped tens of millions of units
  • Highly integrated 77 GHz radar smart transceiver SoC contains four high-performance transmitters, four receivers, a multi-core radar processor with hardware accelerator, Gigabit Ethernet communication interface, and memory
  • Targets the Automotive Safety Integrity Level B (ASIL B) requirements, according to the ISO 26262 functional safety standard and the automotive cybersecurity standard ISO/SAE 21434 to meet the requirements of the automotive industry for safety and security
